Transferring device for optical discs being processed in a disc-making machine, machine incorporating said device and transferring method put into practice thereby

摘要

The described transferring device operates on a machine (2) for producing optical discs (3) comprising several different work stations (7, 8, 9, 10, 11, 12) each arranged to carry out a given operation on the discs being processed. The device (1) performs a sequential transfer of each disc (3) between the different work stations (7, 8, 9, 10, 11, 12) following a path comprising two parallel advance lines, one forward advance line (n) and one backward advance line (n') respectively, which are disposed laterally on opposite sides relative to the longitudinal extension axis of a support arm (14) being part of the device (1). The support arm (14) carries a first and a second series (16, 17) of pick-up heads arranged to execute the optical disc transfer on the forward (n) and backward (n') lines during the forward and return strokes of the support arm, respectively.
